Hey guys, It's been awfully quite here. I hope a can get answers to this question still. I've had abt 2 sets of hyper concrete wheels in storage for abt 2years now without use. I was wondering if I should be worried about them expiring or something. Is that possible with wheels? They still look brand new and nothing outta the ordinary has happen to them.

No. Unless they are edible. It's PU like the shells. Those things you don't really own you just hold on to them / use them. Once we are all gone they are still there; somewhere.^^ And many things will find new contemporary owners. For some time in space.

Yes! They are fully expired and useless! You must get rid of them. Send them to me, so that I can properly dispose of them. :D

I have some Hyperformance wheels that were made over ten years ago and they still ride and slide like a boss. They seem to feel harder than usually, so they may have cured more, but that's subjective and I don't have a problem with harder wheels, anyways.
